@Burgi Probably a dedicated instance class.

Which should be indistinguishable from running it on bare metal, and has the perk of allowing easy and simple scaling.

Burgi

so basically 1 VM per host?

bwDraco

It might be something like a small number of VMs but with the processor cores and disks set aside for particular instances.

(that's how some high-end cloud instances work)

Burgi

isn't there a performance loss with that due to overhead?

i think this is borderline compsci which is something i struggle with

bwDraco

12:21 AM

With modern hypervisors and stuff like IOMMUs, there should be virtually no overhead.

Journeyman Geek

@Burgi because they had them

My house caught fire

Washing machine blew up

No one hurt, some loss of property

I have an exam tomorrow tho

Bob

7:39 AM

@Burgi for varying loads? prolly easier to spin up a couple dozen AWS servers

there will be overhead, and it'll probably cost more than dedis

but for short-term it might be easier

Anyone who migrates stuff from VPS to VPS mind sharing the rough draft of who you do it? A handwritten script? Manually copy stuff? Ansible/Puppet/Cheft/Salt/etc?

djsmiley2k

Configuration in GitHub.

An hour out from Calais

bertieb

Woh?

emailCheck.py - has everyone written one of these at some point? :D

Bob

12:49 PM

@bertieb these days? migrate the storage (zfs) and boot everything (lxd/kvm) on the new host :P

Waiting to board the ferry 😴

Burgi

are you heading home?

did you drive?

djsmiley2k

Lol yes and no.

Coach.

RogUE

Hey guys, could you recommend some colours for the foreground text in the following image(currently the blue text)?

Burgi

black?

what is wrong with the blue?

RogUE

Black is already used for the boundary.

Burgi

1:40 PM

so?

djsmiley2k

Blue contrasts well.

RogUE

Let me try black. It seems to me that the blue doesn't seem good in the image(The image I have posted here is part of a large figure)

I think I will settle with blue, bold text.

rahuldottech

2:42 PM

@RogUE white

Burgi

@rahuldottech white if it has a black stroke around it. we don't know how pale those yellows get

rahuldottech

2:59 PM

@Burgi yes this

You can never go wrong with white text with a black outline for image labeling

Bob

sure you can

it only works when your text is large

at smaller sizes either the stroke is too thin or it drowns out the fill

(or just generally looks nasty/overemphasised)

rahuldottech

@Bob hm. Fair enough

djsmiley2k

I'm on a boat mofos

djsmiley2k

4:11 PM

So in France 15C burning hot sunshine. Come into Dover, get on motorway. Ooh it's sleet.

bertieb

5:25 PM

@Bob To be fair, the VPS I am migrating to probably has enough resources to do something container-y

But the VPS aspect sorta rules out the zfs and (I assume) lxd/kvm aspects

Journeyman Geek

5:58 PM

@bertieb I have a walkthrough for my process for ubuntu

bertieb

Will have a look at the blag

Journeyman Geek

though you could/should probably translate it into a proper config management setup

not on my blag

A: How do I "duplicate" a server?

If all else fails, there's the old fashioned way - On Ubuntu or debian,use dpkg --get-selections to dump out a list of installed packages, and install them with dpkg --set-selections. The equivalent of this for red hat based distros is yum-debug-dump and yum-debug-restore (optionally with --insta...

bertieb

Ah right okay :D

Looks good

'm going from Debian to Arch, so might skip the dpkg stuff

Journeyman Geek

well the idea is to have an idea of what packages you have ;p

so dumping the package list is still useful

bertieb

@JourneymanGeek Aye, I wondered about that, though I think something like Ansible is still a bit overkill

Yes, fair point

Journeyman Geek

6:02 PM

@bertieb well that's vaguely why I have no config management

I have a bunch of one offs

bertieb

But at what point do the one-off add up sufficiently to do something properly manage-y? ;-P

Journeyman Geek

that's the magic question!

I actually want to do that with my next server and router builds

bertieb

Ya! These things accumulate eventually

Oh?

Good way to get feet wet I guess, going from a known and tested process to management-y

Journeyman Geek

@bertieb yup

V.7

Hey all

Could anyone help with figuring out why sound doesn't work in archlinux?
alsa-utils is installed

bertieb

6:07 PM

See, if I could get something that does installation, migration of data, and changes the DNS records in Namecheap... that'd be sweet

@V.7 Tried simple things, like making sure the device you want is being used, and has volume (and isn't muted... been there before) in alsamixer ?

Journeyman Geek

@bertieb I use a dynamic dns client - which is something you probably could roll into config management

bertieb

rubs beard thoughtfully

V.7

@bertieb

There's only Beep

bertieb

@V.7 looks muted to me

but yeah, beep probably isn't what you want

V.7

@bertieb It's Beep

It won't produce any sound in speakers

Journeyman Geek

6:10 PM

@bertieb I'm using ddclient - the config for namecheap ... is somewhere but...

bertieb

@JourneymanGeek I did mean to look at a ddns client, as it would save me clicking to renew my NO-IP dealie every few weeks

Journeyman Geek

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf

protocol=namecheap,
use=web, web=dynamicdns.park-your-domain.com/getip
server=dynamicdns.park-your-domain.com
login=website.com
password='hunter3'
home.website.com

works great

bertieb

Oh boy

Journeyman Geek

not my real website or password lol

bertieb

I can ditch No-IP!

Journeyman Geek

6:11 PM

you will need some config on the namecheap end IIRC

bertieb

@JourneymanGeek Password? I just see star$(^$£)(TWERR_OBVIOUS_JOKE

Will look into it

Journeyman Geek

namecheap.com/support/knowledgebase/article.aspx/583/11/…

official docs

V.7

Any ideas :)?

Already tried everything

Journeyman Geek

@V.7 chat is terrible for questions ;)

V.7

Wasted a day or more

bertieb

6:13 PM

@V.7 Ya. I take it you've been through the Arch Wiki page on ALSA?

Journeyman Geek

Have you tried asking on the main site?

V.7

No, I haven't

bertieb

@V.7 If you've tried literally everything... But yeah, chat can help in a rubber-duck sense ("I've done this and this and that but not... ohhh hey what if I revisit my config and notice that typo")

V.7

@bertieb Already tried that

bertieb

But as JG says it's not the best for questions

Journeyman Geek

6:15 PM

@V.7 chat is good to talk about things. Its terrible for keeping folks attention.

bertieb

Always worth revisiting the wiki; easy to overlook a section, assuming it's not relevant for you or otherwise

@V.7 You can also end up in the middle of an ongoing conversation

Which can make you feel like you're being ignored

There's always the #archlinux IRC channel

But it would behove you to have a list of exactly what you've done / tried / etc

"I've done everything" is a bit... broad

And "Any thoughts?" gets you, well, anything

V.7

@bertieb Already contacted #parabola, #archlinux, #archlinux32 and #linux

About 4 hours and no sound

Might be that there's no guy online who had same issue ofc, yet

bertieb

Why parabola?

V.7

Idk, some guy suggested in #archlinux

Journeyman Geek

@V.7 the problem with chat - well more IRC than here is ~~its two boats passing~~ you have to hope someone who knows happens to be online at the time

bertieb

6:21 PM

Akkk

What shortcut have I hit?

Journeyman Geek

o0

bertieb

Input is being duplicated across all terminals

Journeyman Geek

hm

@V.7 its showing beep. What happens when you hit f6 and switch which input its showing?

bertieb

(somehow grouped all my terminals)

V.7

Journeyman Geek

6:23 PM

hit down and enter?

then test?

V.7

Same

Journeyman Geek

might be you're set to use something other than the onboard sound

tried setting the soundcard you want as a default? alsa-project.org/main/index.php/Setting_the_default_device

djsmiley2k

6:37 PM

Ok firstly for when does one off management became something I should script see xkcd.

bertieb

@JourneymanGeek Is it config management if I do cp /root/.bash_history server_setup.sh after doing this manually? ;-P

@djsmiley2k Fair point :P That said, the xkcd graph lacks "fun" and "useful learning experience" axes :D (sorry for triple ping due to edits)

djsmiley2k

As for no device in also, that maybe means no drivers. Check dmesg and/car/log/messages for mention of your sound card.

Don't know what card you have? lspci and lsusb are your friends. lspci -kk will give you the kernel module too if one's been loaded afaicr.

!!xkcd 1205

ChatBot John Cavil

Don't forget the time you spend finding the chart to look up what you save. And the time spent reading this reminder about the time spent. And the time trying to figure out if either of those actually make sense. Remember, every second counts toward your life total, including these right now.

djsmiley2k

Still on coach, left South Mimms. You all enjoying my journey?

bertieb

6:54 PM

Verily!

I'm trying to figure out how ssh knows my backup server's IPv6 address, when this server's user has no .ssh/config

Oh get lost Clippy

There's an entry in /etc/hosts, must be that, right? No, that's v4 and it points to localhost

WTF have I done here

Maybe if I ls the .ssh dir a few more times the config file will magically appear

Aherm

Maybe if I didn't forget I was testing the thing by sshing in to the backup server, I'd get some sensible results

Nothing to see here, move along

In my defence, the terminal title was still the remote server.... I need to do that thing that varies your hostname colour (which I had configured manually in the past before byobu automatically coloured user@hostname)

Burgi

@djsmiley2k its making targetting you with the drone strike much easier

djsmiley2k

7:19 PM

@bertieb ;D So the server knew it's own IP? ;)

bertieb

@djsmiley2k Error: ambiguous redirect

The backup server points its own name at 127.0.1.1

But the VPS server had the backup server's IPv6 address set correctly

Soo my database dump is 1.2GB for ~~thousands of Wordpress spam that I don't empty from the trash~~ some unknown reason

I should probably do something about that

But at this point some of those spams have nearly reached the age of consent
